Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JoHN G. REBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Boxes, of which the following is a, specification.

My invention relates to what are commonly referred to as folding boxes and the object thereof is to provide such box with simple and eflicient means whereby the box, after bein filled and sealed, can be readily opened either for removing the goods or for the permitting of inspection thereof, such opening of the box bemg done without any liability of damage to the contents. Moreover, according to my invention, a strip is arranged onthe inner sides or surraces of a plurality of the sidewalls of the box to cover and conceal atearing tape or str1n interposed between it and the side walls an also to form a flange for the end or top of the box which becomes torn or detached from the main body ofthe box so far as the particular side walls having the tearing tape orstring are concerned.

In the drawings, Figure 1 is a perspective of a blank from which the box is formed; Fig. 2 a perspective ofthe box in folded condition as to its side walls, but in open condition as to. the end extensions which, when folded, form the top and bot tom covers or closures of the box; Fig. 3 a perspective of the strip which is secured to the side walls-to three of the side walls in. the present instance-and also il .strating the tearing tape or string; Fig. a perspective of the box in complete or assembled form and illustrating the method of open-v ing the box by the pulling of one end of the tape which is herein shown walls; Fig. 5 a.

scale taken on the line 6 6 ofFig. 4.

My invention-may be embodied in folding boxes of different character'and of different construction, but for the sake of a clear and definite description I have chosen to illustrate the same in connection with a-folding box, of rectangular form and made from what is known asdouble-faced corrugated paper board which gives the requisite strength and rigidity for boxes of this character, to be used more as having parparticularly as shipping boxes and the like.

Referring to the embodiment of my invention as illustrated in the drawings the blank from which the box is formed is illustrated in Fig. l and comprises four side walls, 1,v 2, 3 and 4, which are provided at their opposite ends with extensions 1, 3* and 4 which are hinged thereto. The said side walls may be all hinged together by their own material, but by preference I make the fourth wall 4 separate from the others and hinge the same to the side walls 1 and 3, respectively, by the tapes 5 and 6. which when pasted or otherwise secured to said side walls, serve as hinges. inner face or surface of a plurality of these side walls, in the present instance the side walls 1, 2 and 3, and at or near one edge, elther top or bottom edge, of the side walls, I secure in any suitable manner a strip-7', which, as illustrated in Fig. 3, .is composed of three sections hinged together and corresponding in length to the width of said side Walls 1, 2 and 3. In the present instance, and by preference, the outermost edge of this strip comes flush with the top edge of the side walls 1, 2 and 3, and in the present instance also and by preference, this strip is pasted to the inner surface of said side walls by gluing at its innermost edge, thereby leaving the upper or remaining portion of the strip unattached to the side walls, but nevertheless in close or intimate contact therewith.

Between the strip 7 and the side walls is laid or interposed what I will term a tearing tape or strip 8, which is slightly longer than the strip 7, so that its free ends may be extended extraneousof the box andmay be grasped and pulled upon by the operator in the manner and for the \purpose hereinafter described. Although this. tearing tape or strin may besimply laid between the stri and t e side walls, yet it is preferred to position it rather close to the gluing or pasting line so that its innermost edge may be firmly held in such position either by the intimate contact alone of said parts or both by said contact and a small portion of the glue which is expressed between the parts. This strip servesa double function, inasmuch as it not only covers and conceals the tearingtape or strip, but also constitutes a flange projecting from the body of the box after the opening operation hereinafter described. The tearing strip by preference is not made of corrugated paper board such as the body of the box, but of a rather heavy stock of ordinary )aper board, as commonly used in foldin boxes, the weight of the stock being depend ent upon the size and required strength of the box as a whole.

In practice, the box is first set up'to the condition illustrated in Fig. 2, whereupon that end of the box which is to constitute the bottom is closed by folding in the end extensions the extensions from opposite sides being folded inwardly, the narrower sides being preferably folded in first, after which the longer sides are folded and by preference firmly secured to the other pair of extensions in suitable manner, as by pastin or luing, with the result that the end of the box is closed and concealed. The box is now ready to be filled with the goods and after the same are introduced therein those end extensions which are to form the top of the box are folded inwardly and sealed in the same manner as the bottom extensions, as already described. It will be understood that at this time one or both of the free ends of the tearing tape extend extraneous of the box in position to be grasped and pulled by the operator. In this 0 eration the body of the side walls is torn a ong the line on which the tearing tape lies, such tearing line being in a horizontal plane when the box is positioned, as illustrated in Fig. 4, wherein the box is shown as partially torn. A continuance of this tearin operation across all three of the side wal s 1, 2 and 3 will cause a severance or separation between the top end of the box and a small portion of the side walls which remain fastened to the end extensions, the top remainin attached or hinged to the fourth side wal 4 and thereby constituting a lid, as illustrated in Fig. 5. According to this construction, the detached ortions of the side walls now constitute flanges for the lid, while that portion of the strip 7 projectin r above the line of severance of the side walls constitutes a meeting cooperating flange for the flanges of the lid. In this manner and by these means, a foldin r or shipping box of the character describe may be quickly and conveniently opened, notwithstanding the fact that the same has been securely closed and sealed and this without any damage or possibility of injury to the contents of the box. Moreover, the box is not destroyed as the result of the o ening thereof, but on the contrary the top w ich is artially separated or detached from the ody of the box remains as a lid, with the result that the box may be sealed up again in case it had been opened for inspection, or may be continued in use as a container for the goods after being opened by the consumer or jobber.

As hereinbefore stated, the construction illustrated is the preferable one, although, as will be understood, changes or nimlitieations may be adopted without departing from the spirit of my invention. For instance, the stri 7 and the tearing tape 8 may be exten ed so as to cover and cooperate with all four sides of the box, in which event the tapes (3 and 7 could be transversely slotted at the tearing line of the tape.

In practice and as herein shown, where the double-faced corrugated paper boa rd is employed as the material for the box, the corrugations run transversely of the body 'of the box and the tape or string runs parallel with said corrugations, with the result that when such tape or string is pulled, the side walls forming the bed of the box are severed along a line of tie corrugations, such severing action being more easily and readily done with this relative arrangement of the eorru ations and tape or string.

I c aim:
